美国国家航空航天局（NASA）既没有，也不想要核武器。但在阿耳忒弥斯计划将人类送上月球的一个特定指标上，NASA 守口如瓶，仿佛在防止外界破译核密码。
NASA does not have, nor want, nuclear weapons. But when it comes to a particular metric that is part of the Artemis Program to land people on the Moon, NASA guards a particular number like they are trying to prevent outsiders from cracking nuclear codes.
我说的就是在近地轨道为基于星舰的月球着陆器加注燃料所需的星舰发射次数，以便它能飞往月球、着陆并返回月球轨道。
I am speaking of the number of Starship launches required to fuel a Starship-based lunar lander in low-Earth orbit such that it can fly out to the Moon, land there, and return to lunar orbit.
多年来，这个数字一直是个移动的目标。NASA 通常的回应是：“我们不确定，所以不说。”例如 2023 年，时任 NASA 人类着陆系统项目主管的丽莎·沃森-摩根曾对 Ars 表示：“我们有个大致概念，但我不愿透露确切数字。”
This number has been a moving target over the years. The general response from NASA has typically been, 'We don't know for sure, so we're not going to say.' In 2023, for example, the then-director of NASA's Human Landing System, Lisa Watson-Morgan, told Ars, "We have a general idea, but I’m reluctant to say exactly what that is."
